One be deep-bed sintering owing to having auto accumulation heat effect, the bed of material is the thickest, and bottom bed of material sintering temperature is the highest, and the heat that corresponding fire grate bar passes to thermal insulation barriers is the highest, thermal insulation barriers produce thermal deformation the biggest.
Two is big when being the pressure ratio thin bed of material sintering that fire grate bar and thermal insulation barriers bear material during deep-bed sintering.
Three be the midline position of some thermal insulation barriers be the place of two grate furnace grid sections handing-over, midline is relatively big by the load of fire grate bar end, creates bigger tension, compressive stress and shear stress.Add junction, grid section termination and there is gap, thermal insulation barriers entirety is caused to heat up inconsistent, due to without the fire grate bar obstruct to heat near center line, the ignition temperature of sintering deposit directly acts near thermal insulation barriers center line, near center line, temperature rise is apparently higher than other positions, cause the thermal deformation of center line position inconsistent with other positions so that center line position easily occurs that localized burn, stretching, plastic deformation are ftractureed.
Four is some thermal insulation barriers because its width is bigger, and only there is fulcrum (as shown in Figure 1) both sides, pressure at material causes thermal insulation barriers middle part to cave in trolley body direction under the effect of thermal deformation extruding, under thermal deformation repeatedly, and then cause end, center line position to ftracture, cause whole thermal insulation barriers to damage.
During sintering consecutive production; it is to cause to shut down one of principal element changing chassis that thermal insulation barriers damages; thermal insulation barriers just can be changed after must removing baffle plate, fire grate bar after damaging due to thermal insulation barriers; be inconvenient to replacing of starting shooting; replacing chassis can only be shut down; have impact on the seriality of sintering circuit, have impact on yield and the quality of sintering deposit；And easily cause fire grate bar after thermal insulation barriers damage and come off, on the one hand sintering heat is transmitted directly on trolley body, adds the monthly consumption of fire grate bar and trolley body, too increases the consumption of spare part material.On the other hand material will be caused after fire grate bar comes off to be taken away by distinguished and admirable during convulsion, cavity is formed at chassis work surface, cause a large amount of being harmful to leak out from entrance air channel, cavity, while air flow method inequality causes a large amount of raw burn of sintering process, add harmful energy consumption of blower fan.
In prior art, heat insulating piece for sintering trolley improving such as the heat insulating piece for sintering trolley of application number CN201110138895, it is mainly characterized by using and inserted is connected with chassis bicycle beam, it is therefore intended that prevent thermal insulation barriers from coming off.A kind of sintering pallet thermal insulation barriers such as application number CN200920108504, it is mainly characterized by increasing boss in thermal insulation barriers end, make to increase between thermal insulation barriers and chassis body an air barrier, reduce heat and be delivered on chassis body, improve chassis body service life.The increase position of program boss is difficult to control, increases size and is difficult to measuring and calculating, it is difficult to is suitable for various sintering pallet, and still suffers from the problem that position of center line deformed damaged occurs at first than other positions.
Therefore, it is necessary to existing heat insulating piece for sintering trolley is made further improvements.
